Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true, idempotentHint=true, openWorldHint=false and destructiveHint=false, so the safety profile is fully covered elsewhere. The description adds only 'Returns matching tools with links' plus the empty-task listing behavior; it says nothing about match quality, ranking, or what happens when nothing matches. Modest added value against an already-complete annotation set.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The purpose is front-loaded in the first clause, followed by a dense semicolon-delimited catalog and two short operational sentences. The enumeration is long but each item is plausibly load-bearing for semantic matching in a finder tool. Slightly wall-of-text, but no sentence is pure filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description correctly states the return shape ('matching tools with links') and covers the empty-input edge case. The only gap is the undocumented 'limit' parameter, which the schema bounds but does not explain. Otherwise complete for a zero-required-parameter discovery tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 50%: 'task' is documented in the schema, 'limit' is not documented anywhere. The description compensates partially by defining the empty-task semantics of 'task', which the schema does not state, but it never mentions 'limit', its default of 6, or its 1-50 range. Baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb+resource: 'Recommend the right free PrintPal browser tool for a task', then enumerates the covered categories (calculators, generators, mesh utilities, AI generators). An agent can tell it is a catalog/finder rather than a computation. It never names the sibling calculators it overlaps with (calculate_print_cost, calculate_layer_heights, calculate_volumetric_flow), so routing between this and those is left to inference.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

One concrete usage rule is given: 'Pass an empty task to list every tool.' Beyond that there is no when-to-use versus the sibling calculator tools, and no guidance on when a specific calculator is preferable to this finder. Usage is implied rather than stated.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
